Abstract

PURPOSE:To obtain a high efficiency and high fidelity, by providing the 1st and 2nd negative feedback amplifiers plus the 1st and 2nd impedance circuits which are inserted between each of these amplifiers and the load. CONSTITUTION:The input signal is amplified through the 1st and 2nd negative feedback amplifiers 2 and 3, and the full-band component or the low-band component of the output signal of the amplifier 2 is extracted out of the 1st impedance circuit 10 to be supplied to the load 11. And the high-band component of the output of the amplifier 3 is extracted out of the 2nd impedance circuit 14 to be supplied to the load 11. In such way, a high efficiency and high fidelity can be obtained for the amplifier as a whole by using the high-efficiency 1st amplifier 2 and the 2nd amplifier 3 having the excellent high-band property respectively.
